# --description--

Now that you have the data you want, you can use it to populate the UI. But the fetched data contains an array of 26 authors, and if you add them all to the page at the same time, it could lead to poor performance.

Instead, you should add 8 authors at a time, and have a button to add 8 more until there's no more data to display.

Use `let` to create 2 variables named `startingIndex` and `endingIndex`, and assign them the number values `0` and `8`, respectively. Also, create an `authorDataArr` variable with `let` and set it to an empty array.

# --hints--

You should use `let` to declare a variable named `startingIndex`.

```js
assert.match(code, /let\s+startingIndex/)
```

You should set your `startingIndex` variable to `0`.

```js
assert.match(code, /let\s+startingIndex\s*=\s*0\s*;?/)
```

You should use `let` to declare a variable named `endingIndex`.

```js
assert.match(code, /let\s+endingIndex/)
```

You should set your `endingIndex` variable to `8`.

```js
assert.match(code, /let\s+endingIndex\s*=\s*8\s*;?/)
```

You should use `let` to declare a variable named `authorDataArr`.

```js
assert.match(code, /let\s+authorDataArr/)
```

You should set your `authorDataArr` variable to an empty array (`[]`).

```js
assert.match(code, /let\s+authorDataArr\s*=\s*\[\s*\]\s*;?/)
```
